The limitation of novel protected scope.
As shown in Figure 3 to Figure 4, a kind of multi-rotor unmanned aerial vehicle vertical folding mechanism, including：Bearing 1, fold gag lever post 2, bullet
Spring 3, spring retainer bar 4 and cantilever connection block tongue 5；
Fold gag lever post 2 and spring retainer bar 4 is slidably arranged in the both ends of bearing 1, the precommpression of spring 3 limits installed in spring
Between position bar 4 and folding gag lever post 2；Overcome the elastic force of spring 3, push the spring gag lever post 4 moves to the direction for folding gag lever post 2
It is dynamic, release the limitation to cantilever locking block tongue 5.
Cantilever connection block tongue 5 is inserted in the cavity of bearing 1, and its one end is hinged on bearing 1 by folding shaft 8 and limited close to folding
In the side wall of position bar 2, it can be rotated around folding shaft 8；When cantilever rotates horizontal level, cantilever connection block tongue 5 is limited in folding limit
The lower section of position bar 2, is no longer able to rotate, and completes the locking to cantilever connection block tongue 5.
The one end of cantilever connection block tongue 5 away from bearing 1 is connected with cantilever 6, and bearing 1 is arranged on body platform 7, cantilever 6
Block tongue 5 and bearing 1 are connected by cantilever and realize connection with body mounting platform.
In the present embodiment, bearing 1 is provided with chute 11, and the both ends for folding gag lever post 2 and spring retainer bar 4 are arranged on chute
In 11, and the both ends for folding gag lever post 2 and spring retainer bar 4 are arranged in the side wall at chute 11 by nut respectively, not only
It can prevent from folding and be skidded off in the chute 11 of gag lever post 2, and also ensure folding gag lever post 2 along chute 11 slidably.
The installation site of spring retainer bar 4, can be according to the elastic force and the specification of spring needed for folding gag lever post 2, adjustment peace
Holding position, after selecting the installation site in chute 11, fixed by nut, realize the adjustable installation of spring 3.
In the present embodiment, spring retainer bar 4 is provided with spring retainer block 41, and spring 3 is connected on spring retainer block 41, bullet
Spring gag lever post 4 increases spring retainer block 41 and provides mounting platform for spring 3, spring 3 is connected to spring by mounting plane and limits
On the bar 4 of position, it is also convenient for being provided with manhole, passes through folding gag lever post 2.
Spring retainer block 41 is provided with manhole, folds gag lever post 2 and coordinates with manhole gap, ensures that folding is spacing
Fricton-tight friction between bar 2 and spring retainer block 41.
It is appreciated that：It can also use and pass through Milling Process, spring 3 is added with the position that spring retainer bar 4 abuts
Work is into plane.
In the present embodiment, fold gag lever post 2 include one parallel to chute 11 montant 21 and one perpendicular to chute 11 horizontal stroke
Bar 22；Montant 21 is socketed with spring 3, and in one end insertion spring retainer block 41, relative with respect to spring retainer bar 4 can slide,
Adopt the structure, the pretightning force of spring 3 can be adjusted, moreover it is possible to ensure that spring 3 is installed parallel to chute 11, make folding gag lever post
2 slide steady, no tilt phenomenon generation.

The installing space of bearing 1 is limited, will fold after gag lever post 2 decomposes installation, and is assembled in bearing 1, improves installation effectiveness.
As shown in Figure 5：When cantilever 6 needs to be folded down, operator needs to overcome the elastic force of spring 3 to promote the edge of cross bar 22
Chute 11 moves to the direction of spring retainer bar 4, cantilever connection block tongue 5 is departed from the limitation of cross bar 22, releases its lock-out state, hang
Arm 6 under gravity, falls and folded naturally, and shown in the state diagram 2 after cantilever folding, after the completion of folding, spring 3 recovers certainly
Right state, folding gag lever post 2 is set to return to initial position.
As shown in Figure 6：When cantilever 6 needs expansion, operator is boosted cantilever 6 upwards, when cantilever connection block tongue 5 with
When folding the contact of gag lever post 2, cantilever is continued to press on, cantilever 6 overcomes the elastic force of spring 3 to promote folding gag lever post 2, when cantilever 6
When being pushed into level, the resilience of spring 3, fold gag lever post 2 and reset, it is locked that cantilever is connected into block tongue 5 automatically by cross bar 22.Cantilever 6
State after horizontal development is as shown in Figure 1.
The utility model multi-rotor unmanned aerial vehicle vertical folding mechanism, operator only need upwards to boost cantilever, and spring is
It can be automatically locked, realize that cantilever deploys.During folding, operator, which promotes, folds gag lever post, and cantilever under gravity, falls naturally
Under, realize and fold.Its technique is simple, and cost is cheap, easy to operate.
It is last it is to be noted that：Above example is only to illustrate the technical solution of the utility model, rather than it is limited
System.Although the utility model is described in detail with reference to the foregoing embodiments, one of ordinary skill in the art should manage
Solution：It can still be modified to the technical scheme described in foregoing embodiments, or which part technical characteristic is entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the utility model
The spirit and scope of technical scheme.
